Abstract

Disclosed is a method to achieve high initial tack in a composite pressure-sensitive adhesive. The composite adhesive would be made up of both acrylic-based and rubber-based commercially available pressure sensitive adhesives. This composite adhesive system would be applicable to flexible foams, labels, nameplates, etc.

High Initial Tack Composite Adhesive

      Disclosed is a method to achieve high initial tack in a
composite pressure-sensitive adhesive.  The composite adhesive would
be made up of both acrylic-based and rubber-based commercially
available pressure sensitive adhesives.  This composite adhesive
system would be applicable to flexible foams, labels, nameplates,
etc.

      The composite adhesive would consist of alternating stripes
(width variable) of acrylic and rubber-based pressure-sensitive
adhesives (many other patterns are possible in addition to stripes).
The rubber-based adhesive would provide the high initial tack to hold
the part in place initially while the acrylic adhesive would provide
the long term holding properties.  This system is of particular use
on difficult to bond substrates such are coarse surfaces or low
surface energy materials.  A typical composite adhesive applied to a
flexible foam master slice is shown in Fig. 1.  Specific parts would
be die cut from the master slice leaving the composite adhesive
system intact on the to-be-bonded surface (see Fig. 2).
